Use someone else's vibrator? No. If desperate I can always go the old-fashioned way.
My best friend and I like to sex-toy shop together but we don't share. It's always a fun day, we then have lunch after shopping and talk about - ready? - sex. We don't even have to include men in the conversation, we can descant on our cunts and clits and all their workings and pleasures indefinitely. Well, not really, at some point we need to jack off (so far separately).
